Direct access to pyrrole anhydrides via oxidative self-coupling of pyrrole carboxaldehydes
DOI: 10.1039/D4OB00052H, Paper
An elegant synthesis of pyrrole-2-carboxylic acid anhydrides from pyrrole-2-carboxaldehydes using TBAI as a catalyst and tert-butyl hydroperoxide (TBHP) as an oxidant is described herein.
